Selden S30+ Single Soft Attachment Block – 30 mm Ball Bearing Block

The Selden S30+ single soft attachment block is an upgraded version within the S30 range, developed for applications where higher loads are required without sacrificing weight and flexibility. Compared to the standard S30 block, this S30+ model offers significantly increased working and breaking loads.

Instead of a traditional shackle, the block is attached using a line or soft shackle, allowing flexible positioning and optimal load alignment. This reduces stress on the system and improves efficiency in dynamic sailing conditions.

The 30 mm sheave combined with a ball bearing system ensures smooth rotation with minimal friction, even under higher loads. The compact and lightweight construction makes it suitable for both performance dinghies and small keelboats where reliability and efficiency are essential.
